Standing at 435 meters, Milad Tower in West Tehran is the tallest structure in the country and the sixth-tallest free-standing telecommunications tower in the world. Construction on the site officially began in 2000 and ended in 2007, but the tower was inaugurated a year later.

The 12-floor multipurpose structure is home to an observation deck, a revolving restaurant, and a sky dome, apart from various TV, radio and traffic control sections.

While some officials want to present Milad Tower as the symbol of Tehran, most people consider Azadi Tower as the city's icon.

Also located in West Tehran, Azadi (Persian for liberty) was built in 1971.

With its white marble exterior, the 45-meter tower's iconic shape (resembling an inverted Y) is a blend of 1960s architecture with traditional Iranian influences.

The structure, which houses a museum, was closed to public following the 1979 Islamic Revolution but reopened in 2006.

Tughrul Tower is a 12th-century monument located in Shahr-e Rey in southern Tehran. The 20-meter tall brick tower is the tomb of Seljuk ruler Tughrul Beg who died in 1063.

The tower had a conical dome, which would have added to its height but collapsed during an earthquake.

Experts believe that the building also functioned as a clock and one could tell the time of the day from the shape of sunlight on its knurls.

Old Tehran

Tours of Old Tehran take tourists to the historical textures of the capital, which is mostly in the city's District 12.

Tehran's famed Grand Bazaar and the National Museum of Iran are other important sites of attraction in Old Tehran.
